Sensors positions

There were 9 different experiment corresponding to different geometrical structure of exchanges between sensors. These experiments are represented in the following figure (Figure 1) :

Figure 1

Analysis of data

For each experiment, the position of each sensor is described as the mean +/- sd of their x, y and z values. These mean positions are stored in a list for each experiment and used to construct 3D plots of each sensor position.

Results

Tables of means +/- sd x, y, z positions for each sensor at each experiment

3D graphs

As we can see on these graphs, sensor 3310 tends to be misplaced especially on the z-axis Further data exploration should be undertaken for example to exclude data situated at the beginning and end of recording sessions or verify how sensor 3310 behave during further experimental procedures.
